Glass micro fiber cryogenic

Cryogenic insulation paper/radiation shield compositions:

Cryogenic insulation paper(P paper/Z paper)/aluminum foil(or aluminized polyester film) compositions are laminated of Cryogenic insulation paper and aluminum foil(or aluminized polyester film).These products can be wrapped to the cryogenic inner tank directly and no need to composite by user.  Therefore ,it can effectively reduce the waste of material and hugely increases efficiency. The width varies from 40mm to 1800mm.

Q:I would like to ask the electric water heater is good or good gas
At present, there are two kinds of water heater suitable for household use in the market. The utility model is characterized in that the fuel gas water heater is divided into liquefied petroleum gas, artificial gas and natural gas, and the electric heating type water heater also comprises a water storage type and a hot type type.
Q:Why can't a gas stove use natural gas?
Speaking from the combustion characteristics, natural gas and other gas does not have interchangeability, and therefore the conversion of gas to natural gas, it must be the original stove, appliances, meters, transmission and distribution network to replace or transform. The artificial gas burner should be reformed or updated for natural gas appliance, household appliances, by replacing the nozzle into a gas stove fire cover. The household water heater by replacing the nozzle (the main fire, burning fire) burner into natural gas water heater.
Q:Why does the gas smell
So where does the gas come from? When coal is burning in the stove, air enters the furnace from the lower part of the furnace. As a result, the following carbon can get sufficient oxygen, burn completely, produce carbon dioxide, and produce a lot of heat. It is easy to produce gas when the combustion is incomplete. For example, just lit the stove, or the fire was extinguished, or when the door is closed due to fire, the temperature is relatively low or insufficient supply of oxygen, the combustion is not fully, will produce gas.
Q:How to do natural gas leakage
Do not put flammable and explosive articles around the gas stove, do not put heavy pressure on the gas pipeline. It can be used to check whether the leakage of the stove, the pipe and the connecting hose. Put the soap water on the outlet hole of the stove, or the connecting port of the pipe, the hose and the cooker.Should pay attention to, don't hang dishcloth, natural gas pipeline in the wet towel wet goods. For a long time to put these wet clothes, the pipeline is easy to rust, but also broken. A wet rag with salt or acid can also corrode iron pipes and shorten the life of pipes.
Q:What is the proportion of natural gas?
Cubic meters of natural gas combustion heat value of 8000 kcal to 8500 kcal. The calorific value per kilogram of liquefied petroleum gas is 11000 kcal. The specific gravity of liquefied petroleum gas is 0.55. Combustion heat value per cubic meter is 25200 kcal. Each bottle of liquefied petroleum gas weighs 14.5 kg, a total combustion calorific value of 159500 kcal, equivalent to the combustion heat value of 20 cubic meters of natural gas.
Q:Gas stove in water, hit the fire, how to do ah
Gas stoves in the daily cleaning or use, often encountered accidentally put the water or soup, such as liquid spilled into the gas stove on the stove eye, resulting in a gas stove not fire, thus affecting the normal use.
Q:What is the weight of a normal bottle of gas?
In accordance with national standards, domestic liquefied petroleum gas cylinder weight of 15 kg, liquefied petroleum gas filling volume of up to only enough to calculate the amount of 14.5 kg (allowing positive and negative errors of 0.5 kg)
Q:Explain the cause of the expansion of the volume of natural gas after decompression
There is an interval between molecules. When the pressure increases, the space between the molecules becomes smaller and the volume becomes smaller. When the pressure decreases, the gap between the molecules becomes larger and the volume becomes larger
Q:What are the natural gas charges paid by the unit,
If it is the office of enterprises included in the "management fees - Office fees" subjects, canteens included in the "management fees - benefits" subjects, the production workshop is included in the "manufacturing costs", etc.
Q:What is the density of natural gas
1 density and relative densityUnder normal temperature and atmospheric pressure, the density of methane is 0.7174kg/m3, the relative density is 0.5548.The density of natural gas is generally 0.75 kg/m3 ~ 0.8kg/m3, the relative density is generally from 0.58 to 0.62.2 ignition temperatureThe ignition temperature of methane is 540.3 combustion temperatureThe theoretical combustion temperature of methane is 1970.The theoretical combustion temperature of natural gas can reach 2030.
